-LRB- CNN -RRB- -- Marilyn Edge was supposed to turn over her son and daughter to her ex-husband in Georgia .

Instead , police allege , she fled with the children to Southern California and killed them .

On Saturday night , the bodies of the children -- Jaelen , 13 , and Faith , 10 -- were found in a hotel in Santa Ana , California .

Edge , 42 , was apprehended Saturday night after apparently trying to commit suicide by crashing her car at a Home Depot parking lot in a nearby town , police said .

Authorities in Orange County have charged Edge with the children 's murder . She was scheduled to appear in court Tuesday in Santa Ana to enter a plea to the charges but her arraignment was delayed -- with her attorney agreeing to the delay -- until October 25 .

Her ex-husband , Mark Edge , is hospitalized at the VA hospital in Decatur , Georgia , his attorney Marian Weeks said .

The former couple had been fighting a years-long custody battle over the children .

Weeks told CNN affiliate WSB that Marilyn Edge had abruptly left court last week after a judge 's custody ruling did not go in her favor .

Under the order , she was meant to hand the two children over to her ex-husband at Cobb County Police Headquarters in Georgia .

`` When Judge Leonard was giving his order on Wednesday afternoon , she got up and left the courtroom in the middle of it , so that was the ultimate message to Judge Leonard : ` I 'm not going to listen to what you have to say . ' '' said Weeks .

Weeks said she expressed suspicions to her client that Marilyn Edge might flee .

`` I 'd even said to him I thought she 'd take the kids to California because she 'd lived in California in the past , '' she said . `` But neither of us thought she 'd kill the children . ''

Marilyn Edge , from Scottsdale , Arizona , has been charged with two felony counts of special circumstance murder in the deaths of the two children , the Orange County District Attorney said .

If convicted , she faces a minimum sentence of life in state prison without the possibility of parole . The special circumstances cited by prosecutors include committing multiple murders and murder by poisoning .
